I'm sorry but this thread makes me want to cry and even more sure I would like to be steralised asap.
However, Nat I expressed my relief at having small for dates babies. My boys together weighed the same as Whiskey???!! and I am a tall lass. Yet, I know 5 footers who have had and delivered 10lb babies naturally.
10lb isn't an uncommon size these days. I expect you will be offered some more scans towards the end of your pregnancy. Definitely at 32 weeks, and possibly again at 36! YOu have to think, its only really padding, so as long as you birth a head, which you have done already, you should be able to deliver bigger babies. SO my relief at having small babies makes no difference, if you can deliver a 5lber you can deliver an 8lber.
